For my research I want to extract the features of 40 different VOIs. Most ideally, I would like to save the outcome of the features automatically into a csv file. For 1 VOI this is no problem. But my question is, is it possible to save the new outcome to the same csv file everytime the code is runned?  
So that I only have to change the name of the VOI, run the code 40 times and end up with 1 csv file with all the outcomes?

Thank you!

You can automate all the steps that you do in the Slicer GUI using Python scripting. The [Slicer Script Repository](https://slicer.readthedocs.io/en/latest/developer_guide/script_repository.html) and [Developer Tutorials](https://slicer.readthedocs.io/en/latest/developer_guide/api.html#tutorials) page are good starting points.
